Brazil’s World Cup dream was smashed into oblivion as majestic Germany ran riot to win an extraordinary semi-final 7-1 and send the South American hosts crashing to their worst ever defeat in their 100-year footballing history.

Sixty-four years after Brazil was plunged into national mourning after their loss in the 1950 final, the hosts were torn apart in a defeat likely to be every bit as traumatic as the fabled “Maracanazo.”

A section of the crowd chanted sexually-expletive obscenities against the team and President Dilma Rousseff, who up to now had enjoyed a reprieve from protests over the record US$11 billion spent to host the tournament.

Across the nation, others fans shouted at their televisions and abandoned public screenings.

Though Brazil rallied at the start of the second half, the torture continued on 69 minutes when Andre Schuerrle swept in Germany’s sixth.

This time boos rang out around the Mineirao as the Germans celebrated.

Schuerrle then grabbed his second on 79 minutes to make it 7-0, and confirm the worst defeat in Brazil’s history.

The previous record loss had been a 6-0 reverse to Uruguay in 1920.

Schuerlle’s second goal was greeted by a burst of applause as Brazilian fans saluted Germany’s wonderful exhibition of attacking football.

A late goal from Oscar was barely applauded by the Mineirao Stadium crowd.

Brazil had gone into the match riding a fervent wave of national emotion, determined to clinch a place in the final to honour injurect striker Neymar.

The crowd roared chants of “Neymar, Neymar” just before kick-off, following a spine-tingling rendition of the national anthem that saw captain David Luiz proudly holding up the injured striker’s No.9 shirt.

But Mueller’s early strike punctured the fervent mood, and when the goals started flying in after Klose made it 2-0 there was no way back for Brazil.

Germany will now play the winner of Wednesday’s semi-final between the Netherlands and Argentina in the final.

Don't care anything about football (what Americans, when being polite, call soccer) that said I was delighted to see Brazil fail miserably. This loss has political implications. The feckless, left wing Rousseff was already under fire for neglecting basic services and harming the economy with irresponsible sports boondoggles (World Cup to be followed by another impending financial disaster known as the 2016 Summer Olympics.) A world cup success might have saved Rousseff's sorry political fortunes, fortunately though Germany's soccer team has probably saved Brazil from more leftist incompetence and will ultimately lead to better governance and improved economic conditions for ordinary Brazilians.
